"I always felt, even before I got pregnant, that it's better to accentuate your curves," Miller says. "A lot of women try to tuck their butt in or kind of slouch because they're trying to hide. Obviously, you can't suck it in, but it's important to really show off the belly. For some reason, for me, from the side it looks the biggest, so that's what I tried to do."

The former Victoria's Secret angel also says she's not only proud of her body, but has accepted the changes that come with pregnancy. "I had never even owned a scale before, but gaining weight is part of charting your progress," she says. "Yes, I was seeing numbers I'd never seen before, but I let go of that because I had a new goal and focus. It's an adjustment, but it helps having a lot of positive support."
